$300 PC, sitting dedicated for that, is no different from an X-box or other gaming rig
Not quite true, There are alot more games available for PC than there are for any of the game boxes, many for free.A $300 PC ain't exactly a gamer, unless you like really old simple games and have an old OS to play them in.Finally I can't stand the controllers that come with modern game boxes.There literally hundreds of PC games that can be played comfortably with nothing more than a mouse and keyboard.
I would not know... I am not much of a gamer. I bought my Macs to use as tools. I use a windows emulator to run the only MS Windows program I own, Flight Sim 2000... because it is not Mac supported...
I also use Office and wish I had a good alternative... besides that, I only use Mac compatible programs. My wife picked up one of my QuarkExpress CD's, and loaded it onto her G3 PowerBok. She sat down and built an eBay design in a couple of hours with no training, other than her Mac acquired skills... All of Mac programs usually use the same keystrokes, the same linear function, and GUI. The programs are more intuitive in their uses, and act as if they are built together with the OS.
You would think that Apple planned it that way! (sarcasm off)

You can also hack an X-Box and make a pretty decent PC out of it if you get bored with games.
